Cyrtocapsus femoralis Reuter

( Figs. 23, 24 , 69, 70 )

Cyrtocapsus femoralis: Reuter, 1892: 394 (original description; Venezuela); Carvalho 1957: 96 (catalog, in part, distribution from original description only); Schuh 1995: 542 (catalog, in part, distribution from original description only), 2002–2013 (catalog, in part, distribution from original description only); Cazorla-Perfetti 2021: 13 (distribution; hosts apply to C. elutipes ).

Diagnosis. This distinctive species ( Figs. 23, 24 ), misidentified by all authors since its original description (see discussion under C. elutipes ), is distinguished by the dark brown dorsum with the embolium and apical area of the corium pale brown or brownish orange, and the mostly dark brown femora with only the bases of the front and middle femora and the basal half of the hind femur pale, and the basal fourth of all tibiae dark brown.

It is similar in general body color to C. fiuzai ( Figs. 25, 26 ), C. intermedius ( Fig. 34 ), and C. metafemoratus ( Figs. 40, 41 ). It differs from C. fiuzai and C. intermedius in having all the femora apically fuscous (rather than uniformly pale) and the different parameres. It most closely resembles C. metafemoratus but the latter differs in having only the hind femur darkened.

Description. Male ( Figs. 23, 24 ) (n = 3; lectotype male measurements in parentheses): Length to apex of membrane 3.20–3.36 mm (3.42 mm), length to base of cuneus 2.21–2.34 mm (2.30 mm), widest width across hemelytra 1.31–1.38 mm (1.38 mm). Head: Width 0.80–0.82 mm (0.80 mm), interocular width 0. 40 mm (0.40 mm). Labium: Length 0.74–0.75 mm (0.75 mm. Antenna: Segment I length 0.43–0.46 mm (0.48 mm); II, 0.50–0.56 mm (0.56 mm); III (n = 2), 0.35– 0.37 mm (0.38 mm); IV (n = 1), 0.70 mm (0.75 mm). Pronotum: Median length 0.90–0.94 mm (0.91 mm), basal width 1.22–1.25 mm (1.23 mm).

Coloration: Head with vertex and frons black, clypeus and sides yellowish to brownish orange, and underside dark brown; eyes dark reddish brown. Labium dark brown. Antenna uniformly pale yellowish white. Pronotum uniformly black. Scutellum uniformly black. Hemelytron: Clavus black, with apex whitish; corium dark brown becoming paler brownish orange on apical third; embolium yellowish orange; membrane, including inside of areole, translucent white, veins brown. Ventral surface of thorax black; abdomen fuscous with genital capsule dark brown. All coxae whitish; front and middle femora dark brown, with basal fourth of each pale, hind femur dark brown with basal third pale; tibiae pale, dark brown on basal third of each; tarsomeres I and II pale, tarsomere III and claws brown.

Texture and vestiture: Head shiny, finely rugose; densely covered with silvery, sericeous setae, especially along median line and inner margins of eyes. Pronotum shiny black, evenly punctate; calli prominent, divided by a groove and deep pit; anterior third around collar and calli with dense, silvery, sericeous setae, disc with dense, silvery, more slender, sericeous setae. Scutellum finely and evenly punctate, with dense silvery sericeous setae. Hemelytron dull, impunctate, with patches of silvery sericeous setae.

Male genitalia: Left paramere ( Fig. 69 ) elongate, shallowly C-shaped, and hooked apically. Right paramere ( Fig. 70 ) relatively thick, elongate, apically rounded, with two indentations laterally.

Female (n = 3): Length to apex of membrane (membrane missing), length to base of cuneus 2.21–2.24 mm, widest width across hemelytra 1.44–1.54 mm. Head: Width 0.82–0.83 mm, interocular width 0.40–0.42 mm. Labium: Length 0.69–0.75 mm. Antenna: Segment I length 0.40–0.43 mm; II (n = 2), 0.50–0.51 mm; III (missing); IV (missing). Pronotum: Median length 0.90–0.94 mm, basal width 1.22–1.28 mm.

Host. Unknown. All published host records for this species should be applied to C. elutipes (which see).

Distribution. Previously described and known only from Venezuela ( Reuter 1892). Mexico is a new country record.

Discussion. Cyrtocapsus femoralis , with the apical third to half or more of the femora and bases of the tibiae dark brown, has been misidentified by all authors since Reuter’s (1892) original description. It is not clear how many specimens Reuter had when describing this species; therefore, for nomenclatural stability, I consider a specimen found in the FMNH collection a syntype, which is designated as the lectotype below.

Reuter’s (1892) description is confusing when he says (translated from Latin) “…femora at bases and legs (tibiae?) about 3/5 at tip and tarsi whitish…” rather than saying femora, except bases, and basal 2/5 of tibiae dark brown…” which would have made it clearer that his name “ femoralis ” referred to the largely dark brown femora.

Type designation. The following syntype male ( Figs. 23, 24 ) is here designated as the lectotype: Label 1 “San Esteban [ Venezuela], E. Simon, III–88”; 2, “Spec. typ.”; 3, “ Cyrtocapsus femoralis n. sp. O. M. Reuter det.”; 4, “Mus. Zool. H:fors, Spec. typ. No. 9833, Cyrtocapsus femoralis Reut. ”; 5 (red label, here added), “ LECTOTYPE ♂ Cyrtocapsus femoralis Reuter , desig. by T.J. Henry ” ( FMNH) .

Other specimens examined. MEXICO: Veracruz: 5 ♂♂, 4 ♀♀, Mexico, Veracruz to Jalapa , 8 Feb. 1948, W.F. Chamberlain (4 ♂♂, 3 ♀♀, TAMU; 1 ♂, 1 ♀, USNM) .
